Saving multiple versions of same return. Is this possible? Have completed a 2019 return but client now wants to see a "what if" scenario involving multiple assets. "what would my tax have been in 2019 if I had _____ versus what my tax liability was without such a transaction?". Transaction involved is very complex and I don't want to even touch the return as it was prepped and filed. Can a second version be saved and used as a "hypothetical version"?
